    I have installed BMR lowering springs, UCA (poly bushings), and mount on my 2010. I've adjusted my pinion to as close to -2 as I think I can get. I'm hearing a faint "whirling" or light rubbing noise coming from my rear end. The faster I go the louder it gets. It's not loud enough to be annoying but I just want to make sure nothing is wrong. I can really hear it when I remove the back seat and take her for a spin.

    Have any of you experienced this after a UCA and mount install? Other than this faint noise, everything else seems to be good to go.

    Thanks!

    Upgraded suspension=stiffer= more NVH transmission. 'new' noises are common.

    I picked up a lot of noise as well when I installed the uca/lca's. Even more with the 4.10's. Just get a louder exhaust and crank up the boost. Between the blower scream and exhaust growl, you wont be able to hear that stuff anymore.

    Hissing/whirling/whining noises are normal. Thumps/rattles/banging noises are not normal.

    I definitely hear a lot more rear end noise with my Steeda UCA and bracket. Thought of laying down some Dynamat under the rear seat around the mounting area.

    I did that, didn't help the NVH very much because the harmonics are vibrating though the whole chassis.
    Definitely made a big difference in the sound of the stock Shaker 1000 (for the better of course)

    I upgraded exhaust, and the noise pretty much went away :rockon:

    so the more i think about it, i'm hearing the sound even when the car is idling and in neutral...the higher i rev the higher it gets. although it sounds like the rear end (coming from back there), there shouldn't be movement inside with it out of gear, correct? i may just take it to the dealership and see what they say...
